Abstract: An electrochemical element in the form of a button cell having at least one lithium-intercalating electrode, wherein the cell cover or the cell cup has an opening which is closed in a sealed manner during the formation process. Once the formation process has been completed, it is opened briefly for gas to escape from the cell, and is then closed in a gastight manner. The cell cover and the cell cup are composed in particular of metal. The opening can be closed by a metal or metal/plastic composite sheet, which is adhesively bonded or welded to the cell cover or to the cell cup.

Abstract: A method for producing a rechargeable button cell having a negative electrode composed of a lithium/indium alloy, a positive lithium/intercalating electrode and an organic electrolyte, a lithium layer and an indium layer are introduced into a negative housing half-section. The positive electrode material is introduced into a positive housing half-section. The two housing half-sections are beaded to form the button cell once the organic electrolyte has been added and a separator has been placed in between, with a seal being inserted between the housing half-sections. A lithium-indium alloy is formed from the lithium layer and the indium layer by storage or a subsequent charging/discharge cycle.
